Introduction The Spotted Owl (Strix occidentalis) is an endangered species that lives in the old growth forests of the Pacific Northwest. This species is declinging in numbers drastically and has been listed on the ESA since 1990. The spotted owl is native to the Pacific Northwest. They are found in Southern parts of Columbia, North Western America, and California. As a result of declining habitat, there are fewer than 100 pairs of Northern spotted owls in British Columbia, Canada, 1,200 pairs in Oregon, 560 pairs in northern California and 500 pairs in the state of Washington.
1) At the turn on the century, government agencies eradicated predator populations in national parks and forests. Getting rid of predators in Yellowstone had many unanticipated problems. One being the population of other species dramatically changes. The number of deer in this reserve grew rapidly due to the lack of grey wolves hunting them. Since more deer were in Yellowstone, vegetation and food resources decreased because of the constant grazing.
In the 1900s the population decreased because of the DDT ( DDT: dichlorodiphenyltrichloroethane) sickness with the eagles. Hunters are a treat to bald eagles because they will shoot them out of the sky. If a bald eagle eats a duck that has been eating lead shots that
Deeply affected by human encroachment into its territory, when the species was declared federally endangered in 1967, only about 12 individuals remained in the wild (Threats to Florida Panthers). Currently there are around 180 individuals in the wild, and the US Fish and Wildlife Commission’s Florida panther plan defines a successful panther population worthy of delisting the species as endangered. Its requirements for delisting are as follows: “Three viable, self-sustaining populations of at least 240 individuals (adults and subadults) each have been established and subsequently maintained for a minimum of twelve years. Sufficient habitat quality, quantity, and spatial configuration to support these populations is retained / protected or secured for the long-term.(fwc panther
Introduction Lizards. What comes to mind? Typically they live on land, in the desert scurrying across the sand. Lots of lizards are fast on land, but this one is fast on water. Not just being able to swim underwater, but being able to sprint directly on the water’s surface.
Introduction Northern Bobwhite Quail (Colinus virginianus) are one of the most influential and important game animals in America. Their popularity has been the driving force behind conservation, research, and even local economic prosperity. The hunting associated with these birds has become a “southern tradition” since these hunts are typically social events. Currently the bobwhite quail is undergoing a long term population decline which has prompted even more conservation efforts and research. Bobwhite quail are extremely sensitive to habitat quality which has recently been used to promote conservation based land management practices.
Sixty years after the extirpation of wolves in the Northern Rockies and Great Plains of America, biologist and ecologist in Yellowstone National Park reintroduced wolves into a declining ecosystem that once thrived during their presence. The reintroduction brought immense controversy into the West and continues to stir outrage among anti-wolf groups. These anti-wolf supporters argue wolves are ruthless predators that cause destruction to natural environments and livestock. Conversely wolf advocates and scientists suggest that wolves are a keystone species that are essential to the natural regulation of our Western ecosystems. Although pro and anti-wolf advocates can agree that wolves have an effect on livestock, ungulate populations and ecosystems,
This essay by Terry Tempest Williams, is describing us first the massacre of the prairie dog that occurred at the Cedar Ridge Golf Course, where over 400 prairie dog where gassed to death. There are 5 species of prairie dog and they are now threatened and might be in extinct in couple of years. The people wanted to exterminate the dogs because they were running the range because they consume a large amount of green grasses and forbs. According to Williams, “Prairie habitat not only for themselves but also for other grassland species. Prairies dog create diversity, destroy them, and you destroy a varied world (p86/87).”
The gray wolf 's expressive behavior is more complex than that of the coyote and golden jackal, as necessitated by its group living and hunting habits. While less gregarious canids generally possess simple repertoires of visual signals, wolves have more varied signals which subtly inter grade in intensity. When neutral, the legs are not stiffened, the tail hangs down loosely, the face is smooth, the lips untensed, and the ears point in no particular direction. Postural communication in wolves consists of a variety of facial expressions, tail positions and piloerection. Aggressive, or self-assertive wolves are characterized by their slow and deliberate movements, high body posture and raised hackles, while submissive ones carry their bodies low, sleeken their fur and lower their ears and tail. When a breeding male encounters a subordinate family member, it may stare at it, standing erect and still with the tails horizontal to its spine. Two forms of submissive behavior are recognized: passive and active. Passive submission usually occurs as a reaction to the approach of a dominant animal, and consists of the submissive wolf lying partly on its back and allowing the dominant wolf to sniff its anogenital area. Active submission occurs often as a form of greeting, and involves the submissive wolf approaching another in a low posture, and licking the other wolf 's face. When wolves are together, they commonly indulge in behaviors such as nose pushing, jaw wrestling, cheek rubbing and facial
The United States of America abounds with beautiful scenery, amazing natural resources, and fascinating animals. Each state can boast of its unique natural resources. The state of Alaska provides an abundant habitat for numerous species of mammals, fish, and birds.
Major League baseball teams and some college leagues use wood bats. College level teams use wood bats when their league is only for wood bats. For example, the Lakeshore Chinooks are in a wood bat league. Some other countries that baseball is popular in are Cuba and Taiwan. Every wood bat is different. They are made with different sizes and weights. The bats can also be made out of different types of wood. Although, most baseball players use maple or ash wood for their bats nowadays. About sixteen-thousand five-hundred bats are used per season. There are three main things that need to be done to make a baseball bat.
Animals in Their New Natural Habitat Why are different species becoming extinct? Do researchers know how many innocent animals are killed each year? When will animals be protected in a comfortable habitat? In man-made environments, such as zoos and other nature parks, animals that are born in the wild are protected and well taken care of. Due to animals running around in the wild, scientists and researchers can track the amount of animals being killed everyday.
